Tensile Property Estimates Obtained Using a Low Compliance Shear Punch Test Fixture

摘要

It has been previously shown that for a variety of BCC and FCC metals, shear punch properties correlate well with uniaxial tensile properties from corresponding miniature tensile tests. However, recent studies of the shear punch test technique using finite element modeling have suggested that large amounts of compliance may greatly affect the shape of the observed load versus displacement trace and the shear yield stress determined from the trace. On the assumption that this would lead to shear punch properties that correlate even better with uniaxial tensile properties, a low compliance shear punch test fixture was constructed. Shear punch tests were performed on a variety of unirradiated metals, and the shear punch properties were compared to tensile properties from corresponding miniature tensile tests. These correlations were then compared to previous correlations obtained using an older fixture with much greater compliance.
